They don't call it Super Tuesday for nothing! Today marks an exciting day in the race to the U.S. Presidency: voters in 24 states will choose their party candidates. This will be the largest number of primaries taking place at one time in the history of the U.S. electoral system.

We've joined forces with Twitter to give you instant updates on Super Tuesday. Instead of sitting on the sidelines, you can send a simple text message about your voting experience. Huge turnout? Taking too long in line? Did you just vote for the first time? We want it all, if you can keep to 140 characters or less. (And if candidates can keep their posts to 140 characters, anyone can.)

Throughout the day, you can watch Twitter updates from across the country:

Twitter posts are only one piece of the Google Super Tuesday Map, a one-stop shop to follow the action today. You can find the latest YouChoose '08 videos, Google News election headlines and primary state results down to the county level. The Google News team is also in on the action. In addition to all the latest stories from thousands of sources in our new election section, they've also put together a gadget that tracks the progress of the candidates in each of the 24 states (of course, the numbers here are not real; they're meant to show you how it may look after the polls close).

Super Tuesday gives us a chance to try out new features and to see how people are using technology to participate in elections. This coming Thursday, we'll post a roundup of highlights. Send suggestions our way to elections at google dotcom.

Update: Gadget results in example are not real numbers or projections.
